PATENTED 0m 5 I972 ATTORNEY HAIR-CURLING IRON BACKGROUND OF THE INVENTION It has been proposed to modify heated curling irons to include means for storing therein volatile hair-treating and conditioning fluid, which fluid is dispensed in vapor form through ports or openings in one arm of the curling iron.

However, such known curling iron includes complex storage means for the volatile fluid, which increases manufacturing costs, requires special refilling procedures and is embodied in a complex construction.

Accordingly, an object of this invention is to provide a haircurling iron of the heated type, which includes improved and simple means for receiving and dispensing volatile treating fluid.

Another object of thisinvention is. to provide a hair-curling iron of the character described, which allows the injection of a limited amount of treating fluid into the iron, sufficient for a single hair curling and treating operation thereby simplifying the fluid carrying means within the iron.

A further object of this invention is to provide a hair-curling iron of the character described, which includes vents or ports arranged in a manner to dispense and apply the treating fluid in vapor form to improve the mode of application thereof to the hair being curled and treated.

Yet another object of this invention is to provide a haircurling iron of the character described, which is economical to manufacture, and easily manipulated in use.

Other objects of this invention will in part part hereinafter pointed out.

be obvious and in DESCRIPTION OF THE DRAWING view taken on the line 2-2 DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in the drawing, designates a hair curling and treating iron, embodying the invention. The same comprises an elongated handle portion 11 of molded synthetic resin and a tubular metal arm 12 extending from the forward end thereof. An enlarged plastic disc 13 is located at the juncture of handle portion 11 and arm 12, and provides means for supporting iron 10 in a tilted position on a supporting surface, when the iron is not in use.

A molded swivel member 14 carrying electrical wiring 15 is suitably connected to the rear end of handle portion 11, in a manner known in the art. The wiringlS terminates in a plug, not shown, for connection to electrical receptacles, not

shown.

The usual spring-pressed arm 16, which is curved transversely to conform to the curvature of tubular arm 12, is pivotally connected thereto as at 17, the arm 16 being formed with pressed out bead portions receivable in corresponding recesses formed in arm 12 at a point adjacent disc 13. Arm 16 includes an actuating portion 18 overlying disc 13 and carrying a finger piece 19, whereby the arm 16 may be pivoted to an angular, open position relative to arm 12, when the iron 10 is in use.

The tubular arm 12 is closed at its forward end by a flanged disc 21 force fitted into arm end 20. A molded resin tip 22 is fitted into the flanged portion of disc 21 and secured by a screw 22A threaded into the center of flanged disc 21.

- 30, 31, said fluid being walled metal tubin 25 is fixedl mounted within tubular arm 12. The wall of tu ing 25 at t e forward portion thereof is pressed inwardly as at 26, 27, over a limited longitudinal extent thereof, to provide a pair of diametrically opposed fluidreceiving chambers 28, 29.

A pair of fluid-filling openings 30, 31 are formed at forward end portions of the wall of tubular arm 12, which communicate with chambers 28, 29 respectively. Thus, volatile treating fluid may be injected into chambers 28, 29 via openings carried in plastic bottles having dispensing tips receivable in openings 30, 31.

The heated vapors of the volatile liquid contained in chambers 28, 29 escape outwardly of tubular arm 12, by way of vents or ports 32. Ports 32 are formed by transversely cutting wall portions of tubular arm 12, which overlie chambers 28, 29. The ports 32 are uniformly spaced along the length of tubular am 12, corresponding to the length of chambers 28, 29.

A gasket 35 seals off the juncture of flanged disc 21 and the forward end of tubing 25.

It will be apparent that the chambers 28, 29 are easily filled with sufficient volatile fluid via filling openings 30, 3 1 the iron 10 being suitably tilted during the filling operation to allow the fluid to pass along the length of chambers 28, 29.

The iron 10 being suitably heated by heating element 23, may be brought to a selected temperature shown by a suitable indicator on the iron, not shown. The fluid is quickly vaporized and escapes through vents 32, on both sides of tubular arm 12. Thus, the hair being engaged by iron 10 in the usual manner, is heated and subjected to the treating fluid simultaneously.

The treating fluid emanating from opposite sides of tubular arm 12, allows for thorough contact with the hair while the same is being heated and manipulated. The treating fluid may be injected into chambers 28, 29 in amounts sufficient for a single hair treatment, thus eliminating the need for storing the liquid in the iron in excessive amounts.

The treating fluids are known in the art, comprising essentially sulfonated alcohols, oleates, oils, lecithin, polyvinyl pyrrolidone, water and the like.

I claim:

1. A hair-curling iron comprising a handle portion, a tubular metal portion extending forwardly from the forward end of said handle portion, an arm pivoted to said tubular portion for angular displacement therefrom, a tubular member fitted within said tubular portion, and a heating element disposed within said tubular member, said tubular member having diametrically opposed wall portions depressed radially inward toward each other over a limited longitudinal extent of said tubular member to form diametrically opposed chamber means for carrying volatile fluid, said wall portions of said tubular portion being formed with a plurality of ports communicating with said chamber means for venting heated volatile fluid in opposite directions.

2. An iron as in claim 1, wherein said tubular portion is formed at the forward end thereof with filling openings communicating with the forward ends of said chamber means.

3. An iron as in claim 1 wherein said ports comprise transversely extending, longitudinally spaced slots formed in a wall portion of said tubular portion said slots communicating with said chamber means. 

2. An iron as in claim 1, wherein said tubular portion is formed at the forward end thereof with filling openings communicating with the forward ends of said chamber means.
 3. An iron as in claim 1 wherein said ports comprise transversely extending, longitudinally spaced slots formed in a wall portion of said tubular portion said slots communicating with said chamber means.
